Can anyone answer this >?

see explanation

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + b

where m is the slope and b the y- intercept

m is the slope of the line and b is constant / y intercept value which shows that the line is passing through origin

f-1(x)= cube root of 19x squared/x

step-by-step explanation:

since the airplane is moving with constant speed then the distance travelled can be calculated by x=u*t

in km/h would be:

x=640*3.5=2.240 km

in m/s would be:

u=640 km/h= 640.000 m/h =640.000/ 3600 m/s =177.8 m/s

t= 3.5 h= 3.5 * 3600 s=12.600 s

then x=u*t= 177.8*12.600= 2.240.280 m
